Description: |
| This patent is listed by some sources as being granted on 11 Jun., 1829.
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“The roller cotton gin consists of two rollers, about sixteen inches in length, which are made to turn something like the rollers of a flatting mill. The seed cotton being forced against these, the cotton is drawn through the rollers, and the seed left behind. Such rollers, it is stated, become heated in use, sufficiently to set fire to the cotton. The improvement claimed is to the making them hollow, so as to admit air freely, which, the patentee avers, will obviate this objection. If desired, a current of air, or even of water, may be made to pass through them.”
